Abstract (en)
[origin: EP0482947A1] The invention provides a magnesium manganese alloy suitable for use in the production of a pellet 10 for administration to a ruminant by dposition in its rumeno-reticular sac. A typical pellet 10 comprises a magnesium alloy tube 12 enclosing a degradable core formed of plurality of tablets 14, 16. The magnesium alloy used in the construction comprises at least 90% by weight of magnesium, uyp to 1% zinc and up to 2% of manganese. Preferably the alloy may further include aluminium, silicon or zirconium along with iron and beryllium. When deposited in an animal's rumen the alloy reacts with the rumen juices to form an anodic film over the exposed surface of the tube 12. This prevents corrosion or dissolution of the tube 12 except at its exposed ends where galvanic corrosion by coupling with the electrically conductive core 14, 16 is provided. The normal requirement of a non-degradable exterior coating e.g. resin for the tube exterior is obviated. <IMAGE>
